"Already, more than half of the world’s population lives in urban areas. By midcentury, that share will grow to two-thirds, the U.N. predicts. This urbanization comes at a cost, though. Infrastructure is strained. Cars are multiplying but roads are not, so congestion is worsening. And the supply of vital resources — energy, clean air and fresh water — is imperiled."
